Hi Barry, Thanks for your reply.

My posted code is simplified to reproduce this problem.
I know how to use Task Queue, but it is too complex for me to join its
results.
So.. I am trying to implement simple fork-join model using direct
Protocol Buffer with makeAsyncCall from SDK 1.2.8.
It worked fine under some instances up, but it failed when no instance
was active.
I have found that url fetch's request to self application causes dead
lock due to spining up and its own request are executed in serial.
any ideas?

Thanks,
WdWeaver
